I have been a Dell user for several years and have been generally happy with the computers.  This week I decided to upgrade with an 8920 that was for sale at Costco.  I purchased one, brought it home, and unpacked it.  The ports for the graphic card were not accessible as the graphic card had been installed at an angle.  I returned it and got another 8920.  After turning it on, the fan came on and was unbelievably loud.  I returned this one and got refunded.  At this point I'm really having some doubts about quality with current Dell products.
